In short, thematters specifying the claimed invention are not limited to particularmembers, structures or the like exemplified by the followingillustrative embodiments. In the following, the illustrative embodimentsare described with reference to the drawings.

First Illustrative Embodiment

1. General Configuration of the Image Forming Apparatus

Referring first to FIG. 1, a housing 103 of an image forming apparatus101 according to the present illustrative embodiment configures a designsurface appearance of the image forming apparatus 101. In the apparatusmain body, namely, in the housing 103, an image forming unit 105 forforming an image on a sheet such as a paper sheet is accommodated asshown in FIG. 2.

It is to be noted that the image forming unit 105 in the presentillustrative embodiment is an image forming unit of the monochromatictype or an image forming member of the xerographic type having aphotosensitive member 105A, a charger 105B, an exposure unit 105C, atransfer member 105D, a fixing unit 105E and so forth.

The photosensitive member 105A carries a developer image thereon. Thecharger 105B charges the photosensitive member 105A. The exposure unit105C exposes the surface of the charged photosensitive member 105A toform an electrostatic latent image on the surface of the photosensitivemember 105A. Then, if charged developer is supplied to thephotosensitive member 105A on which the electrostatic latent image isformed, then a developer image is carried on the surface of thephotosensitive member 105A.

The transfer member 105D is configured to transfer the developer imagecarried on the photosensitive member 105A to a sheet and is disposed ata position opposing to the photosensitive member 105A. The fixing unit105E fixes the developer image transferred to the sheet. It is to benoted that the fixing unit 105E in the present illustrative embodimentis a fixing device of the heating type which heats the developer todeposit the developer onto the sheet.

Then, the sheet for which image formation is completed is dischargedfrom a discharge port 107A to a discharge tray 107. It is to be notedthat the discharge port 107A in the present illustrative embodiment isopen to the forward side at a rearward side upper portion of the housing103. The discharge tray 107 is configured to have an inclined face whichis inclined downward toward the discharge port 107A.

Below the image forming unit 105 in the housing 103, a feed tray 109 isdisposed which has a receiving portion 109A on which a plurality ofsheets can be placed. The feed tray 109 is removably mounted on theapparatus main body, namely, on the housing 103. In the presentillustrative embodiment, the feed tray 109 may be mounted on and removedfrom the housing 103 by moving the feed tray 109 in forward and backwarddirections.

Sheets placed in a stacked state on the feed tray 109 are successivelyfed to the image forming unit 105 from the upper end side of the feedtray 109 in the stacking direction.

2. Antenna Portion for Short-Range Wireless Communication

In the housing 103, a communication board 111 having an antenna portion111A for short-range wireless communication is disposed as shown in FIG.2. Further, the image forming apparatus 101 according to the presentillustrative embodiment carries out short-range wireless communicationwith a communication device such as a portable apparatus (not shown)through the antenna portion 111A. By such short-range wirelesscommunication, for example, the following acts can be carried out.

In particular, (a) the image forming apparatus 101 can be operatedthrough an operation unit of the communication device. (b) Image data tobe formed on a sheet can be transmitted from the communication device tothe image forming apparatus 101 directly without passing through acomputer or the like so that it is printed by the image formingapparatus 101. Or, (c) by authenticating an owner of the communicationdevice, an operation permitted in advance to the owner is executed whileoperations other than the permitted operation are prohibited.

A communication unit 111B which corresponds to the antenna portion 111Ais provided at a position on the outer surface of the housing 103 atwhich the communication unit 111B may be seen without obstruction fromthe upper side as shown in FIG. 1.

In particular, the image forming apparatus 101 does not have any portionabove the communication unit 111B. Therefore, in a region from above thecommunication unit 111B to the communication unit 111B, nothing blocksthe field of vision of the user, and the user may see the communicationunit 111B without obstruction from the upper side.

In particular, the communication unit 111B is provided on an upper faceof a forward side of the housing 103. An operation region 113 which isoperated by a user is provided on the front side of the housing 103. Inparticular, the communication unit 111B in the present illustrativeembodiment is provided, at least in the forward and backward directionof the housing 103, on the same side as the operation region 113.

More particularly, the communication unit 111B is provided at a positiondisplaced toward the front side with respect to the discharge tray 107in the forward and backward direction of the housing 103. It is to benoted that the “front face side in the forward and backward direction ofthe housing 103” is a side of the housing 103 on which the operationregion 113 is provided, for example, with respect to the center in theforward and backward direction.

Therefore, if the antenna portion 111A and the charger 105B areprojected to a horizontal plane, then the antenna portion 111A projectedto the horizontal plane is displaced with respect to the charger 105Bprojected to the horizontal plane. In other words, the antenna portion111A projected to the horizontal plane is positioned on the oppositeside to the fixing unit 105E projected to the horizontal plane acrossthe charger 105B projected to the horizontal plane.

Further, the communication unit 111B is formed in a horizontally planarstate as shown in FIG. 2. It is to be noted that the term “horizontal”signifies a horizontal state of such a degree that, when a communicationdevice is placed on the communication unit 111B, the communicationdevice does not slip down from the communication unit 111B, namely, fromthe housing 103. Further, the term “planar state” signifies a planarstate of such a degree that, when a communication device is placed onthe communication unit 111B, the communication device does not sufferfrom any significant rattle.

Further, an opening 103A and a front cover 103B are provided on theforward side of the housing 103. The opening 103A establishescommunication between the inside and the outside of the housing 103. Thefront cover 103B is assembled to the housing 103 for displacementbetween a position at which the front cover 103B closes the opening 103Aand a position at which the front cover 103B opens the opening 103A. Itis to be noted that the front cover 103B in the present illustrativeembodiment opens and closes the opening 103A by rocking displacementthereof around a lower end side thereof.

The antenna portion 111A is disposed on the upper side with respect toan upper end of the front cover 103B. In other words, the antennaportion 111A is positioned at a location displaced to the outer sidefrom an outer edge of the opening 103A as viewed from the openingdirection of the opening 103A, in the present illustrative embodiment,from the forward and backward direction.

It is to be noted that the opening 103A can allow a dismounting ormounting operation of a process unit 105F or a removing operation of ajamming sheet or the like to be carried out. Incidentally, the processunit 105F is a casing in which the photosensitive member 105A, developerand so forth can be accommodated.

3. Characteristics of the Image Forming Apparatus

In the present illustrative embodiment, since the communication unit111B is provided at a position at which it can be seen withoutobstruction from the upper side, a communication device such as asmartphone can be brought close to or into contact with thecommunication unit 111B readily. Accordingly, since wirelesscommunication between the antenna portion 111A and a communicationdevice can be established reliably, the operability of the image formingapparatus which utilizes the communication device can be improved.

In the present illustrative embodiment, the antenna portion 111A isdisposed such that the antenna portion 111A projected to the horizontalplane is displaced from the charger 105B projected to the horizontalplane. Therefore, the distance between the antenna portion 111A and thecharger 105B may be made comparatively great. Accordingly, a situationin which the antenna portion 111A suffers from electric noise from thecharger 105B may be suppressed.

In the present illustrative embodiment, the antenna portion 111A isdisposed such that the antenna portion 111A projected to the horizontalplane is positioned on the opposite side to the fixing unit 105Eprojected to the horizontal plane across the charger 105B projected tothe horizontal plane. Therefore, the antenna portion 111A can be spacedfrom the fixing unit 105E. Accordingly, where the fixing unit 105E ofthe heating type is adopted, the antenna portion 111A can be protectedagainst the heat of the fixing unit 105E.

In the present illustrative embodiment, since the communication unit111B is provided at a position displaced from the discharge tray 107,such a failure that a sheet placed on the discharge tray 107 makes anobstacle when a communication device is brought close to or into contactwith the communication unit 111B can be prevented.

In the present illustrative embodiment, since the communication unit111B is positioned on the upper face of the forward side of the housing103, the user can bring a communication device close to or into contactwith the communication unit 111B readily.

In the present illustrative embodiment, since the communication unit111B is formed so as to have a horizontal planar shape, a communicationdevice may be left in a state in the communication device when it isplaced on the communication unit 111B. Accordingly, the user need nothold the communication device, and consequently, the image formingapparatus is improved in convenience in use.

In the present illustrative embodiment, since the antenna portion 111Ais disposed on the upper side with respect to an upper end of the frontcover 103B, the user can bring a communication device close to or intocontact with the communication unit 111B readily, independent of theposition of the front cover 103B.

In particular, if the communication unit 111B is provided otherwise on amovable member such as the front cover 103B, then since the position ofthe communication unit 111B is displaced depending upon the state of themovable member, it is difficult to bring a communication device close toor into contact with the communication unit 111B.

Second Illustrative Embodiment

The communication unit 111B in the first illustrative embodiment isprovided at a position displaced forwardly with respect to the dischargetray 107 in the forward and backward direction of the housing 103.However, in the present illustrative embodiment, the communication unit111B is provided at a position displaced with respect to the dischargetray 107 in the leftward and rightward direction of the housing 103 asshown in FIG. 4.

Further, the communication unit 111B in the present illustrativeembodiment is formed in an inclined planar shape which extendsdownwardly toward the forward side. Further, a holding member 111C forholding a communication device thereon is provided on the lower end sideof the communication unit 111B.

It is to be noted that the inclined face of the housing 103 whichconfigures the communication unit 111B may have any configuration. Forexample, the inclined face of the housing 103 may be formed integrallywith a top cover 103C which configures the housing 103 or may be formedas a separate member from the top cover 103C and assembled to the topcover 103C.

Further, the communication unit 111B in the present illustrativeembodiment is formed in an inclined planar shape which is inclineddownwardly toward the forward side. Therefore, for example, where adisplay unit is provided on a communication device, the user canvisually recognize the display unit readily while the communicationdevice remains placed on the communication unit 111B.

Further, in the present illustrative embodiment, since the holdingmember 111C for holding a communication device is provided on the lowerend side of the communication unit 111B, the user need not continue tohold the communication device. Accordingly, the image forming apparatuscan be improved in convenience in use.

It is to be noted that, while the communication unit 111B in FIG. 4 isprovided on the rear face side, namely, on the rearward side withrespect to the center in the forward and backward direction, the presentillustrative embodiment is not limited to this, but the communicationunit 111B may be provided on the forward side.

Further, while, in FIG. 4, the holding member 111C is configured from agroove extending in the leftward and rightward direction, the presentillustrative embodiment is not limited to this, but the holding member111C may be configured, for example, from a projection which projectsupwardly from the top cover 103C or a like element. Or, a flat face ofthe top cover 103C may be utilized as the holding member 111C, or else,the holding member 111C may be eliminated.

Third Illustrative Embodiment

In the present illustrative embodiment depicted in FIG. 5, an imageforming apparatus 101 with which a reading unit 120 for reading in imageinformation described on a manuscript is integrated is shown.

In particular, the housing 103 in the present illustrative embodimentincludes a first housing member 131 and a second housing member 132. Thefirst housing member 131 accommodates the image forming unit 105 andcorresponds to the housing in the first illustrative embodiment.

The second housing member 132 accommodates the reading unit 120 thereinand is positioned at a location spaced above the first housing member131 with a space 130A left therebetween. In short, the reading unit 120is positioned at the location spaced above the discharge tray 107 withthe space 130A therebetween.

Further, at a position of the second housing member 132 displaced fromthe reading unit 120, an operation panel 132A which configures part ofthe second housing member 132 and has the operation region 113 isprovided. The communication unit 111B is provided on the operation panel132A.

Accordingly, if the reading unit 120 and the antenna portion 111A areprojected to a horizontal plane, then the antenna portion 111A projectedto the horizontal plane is displaced from the reading unit 120 projectedto the horizontal plane. Particularly, in the present illustrativeembodiment, the operation panel 132A is displaced frontward with respectto the reading unit 120 and is provided at a position at which theoperation panel 132A can be seen from the upper side withoutobstruction.

Therefore, in the present illustrative embodiment, the user may bring acommunication device close to or into contact with the communicationunit 111B readily without being obstructed by the reading unit 120.

Further, since the communication unit 111B is provided on the secondhousing member 132 disposed on the upper side with respect to the firsthousing member 131, the user can bring a communication device close toor into contact with the communication unit 111B readily from the upperside.

Although the communication unit 111B in the present illustrativeembodiment is configured in an inclined planar shape similar to that inthe second illustrative embodiment, the holding member 111C is notprovided on the communication unit 111B as shown in FIG. 5. However, thepresent illustrative embodiment is not limited to this, but the holdingmember 111C may be provided otherwise on the lower end side of thecommunication unit 111B or the communication unit 111B may otherwise beformed in a horizontal planar shape.

Further, where the holding member 111C is provided, it may be configuredsuch that, for example, as shown in FIG. 6, a recessed portion 111Dforms a recess in the upper face of the operation panel 132A that allowsa communication device to be received therein. If such a configurationas just described is adopted, then since a communication device can fitinto the recessed portion 111D, the recessed portion 111D can functionas the holding member 111C.

Fourth Illustrative Embodiment

While, in the third illustrative embodiment, the communication unit 111Bis provided in the second housing member 132, in the presentillustrative embodiment, the communication unit 111B is provided at aposition of the first housing member 131 at which the communication unit111B can be seen without obstruction from the upper side as shown inFIG. 7.

Also in the present illustrative embodiment, if the reading unit 120 andthe antenna portion 111A are projected to a horizontal plane, then theantenna portion 111A projected to the horizontal plane is displaced withrespect to the reading unit 120 projected to the horizontal plane.

Therefore, also in the present illustrative embodiment, the user maybring a communication device close to or into contact with thecommunication unit 111B readily without being obstructed by the readingunit 120.

While the image forming units in the first to fourth illustrativeembodiments described hereinabove are of the monochromatic xerographytype, the present disclosure is not limited to this. In particular, theimage forming unit may be of any type such as the color xerography typeor the monochromatic or color ink jet type.

Further, the particular utilization form of the short-range wirelesscommunication is not limited to that used in the illustrativeembodiments described hereinabove but may be any other utilization form.

For example, a communication device having a display unit such as aliquid crystal panel may be used in such a utilization form that thedisplay unit of the communication device functions as a display unit ofthe image forming apparatus through short-range wireless communication.Where the communication device is used as the display unit of the imageforming apparatus, a configuration wherein the image forming apparatusdoes not have a display unit can be implemented. Therefore, reduction ofthe fabrication cost of the image forming apparatus can be anticipated.

In thefollowing, a configuration of the ink jet printer 1 which relates to theshort-range wireless communication is described.

Referring to FIGS. 8 to 11, a terminal receiving member 39 on which thecommunication terminal 200 can be placed is provided in the dischargeunit 6. In particular, the terminal receiving member 39 is a recessedportion provided on the discharge tray 15 b on which a recording papersheet 100 recorded by the printer unit 4 is to be placed as shown alsoin FIG. 12. Further, the terminal receiving member 39 is formed in asubstantially rectangular shape at a central portion at a front endportion of the discharge tray 15 b. Furthermore, the terminal receivingmember 39 has an extent sufficient to accommodate the communicationterminal 200 therein and has a depth with which the communicationterminal 200 does not project upwardly from the terminal receivingmember 39 in a state in which the communication terminal 200 is mountedin the terminal receiving member 39. The user can place thecommunication terminal 200 readily into the terminal receiving member 39from the front of the discharge unit 6. Below the terminal receivingmember 39 of the paper cassette 15, a mark 40 which indicates theposition of the terminal receiving member 39 and is, in the presentillustrative embodiment, an arrow mark, is applied.

According to FIG. 10, an antenna 41 serving as a communication unit maycommunicate by the NFC with the communication terminal 200 received inthe terminal receiving member 39. In particular, the antenna 41 is aloop antenna and is disposed on a lower face, namely, the reverse face,of the panel controlling board 38. Further, the antenna 41 is disposedon a lower face of the panel controlling board 38 disposed in asubstantially horizontal posture such that the loop portion thereof liessubstantially in parallel to the horizontal direction. Further, theantenna 41 is disposed substantially directly above the terminalreceiving member 39 such that the distance L between the terminalreceiving member 39 and the antenna 41 is within 10 cm which is amaximum communication distance by the NFC. Another loop antenna notshown is built in the communication terminal 200 such that the loopportion thereof extends in parallel to a direction perpendicular to thethickness direction of the communication terminal 200. Therefore, if thecommunication terminal 200 is installed on the horizontal bottom face ofthe terminal receiving member 39, then the loop portions of the antenna41 of the ink jet printer 1 and the antenna of the communicationterminal 200 oppose substantially in parallel to each other.

If the communication terminal 200 is received in the terminal receivingmember 39, then communication by NFC is carried out between the antenna41 on the ink jet printer 1 side and the antenna on the communicationterminal 200 side. More particularly, if a magnetic field is generatedfrom one of the loop antenna 41 of the ink jet printer 1 side and theloop antenna of the communication terminal 200 side, then inducedcurrent is generated in the other antenna by electromagnetic induction.Consequently, data is transmitted from the one antenna to and receivedby the other antenna. Then, if the transmission (magnetic fieldgeneration) function and the reception (induced current generation)function of both antennae are changed over alternately, thenbidirectional communication can be achieved between the ink jet printer1 and the communication terminal 200.

Now, an electric configuration of the ink jet printer 1 is described.FIG. 13 is a block diagram schematically showing an electricconfiguration of the ink jet printer 1. Referring to FIG. 13, thecontrol board 29 for controlling operation of the ink jet printer 1 isconnected for data communication with a PC (personal computer) 300,which is an external apparatus, through an input/output interface (I/F)71 such that recording data of an image or characters to be recorded areinputted from the PC 300 to the control board 29. Further, the panelcontrolling board 38 in which the panel controlling circuit 81 isincorporated is connected to the control board 29 such that variousoperations from the operation panel 9 are inputted as various signalsrelating to operation of the ink jet printer 1 to the control board 29through the panel controlling circuit 81.

Various circuits are incorporated in the control board 29. Inparticular, a recording controlling circuit 72 for controlling recordingoperation of the printer unit 4, which includes the ink jet head 18 andso forth, based on received recording data, and a paper feedingcontrolling circuit 73 for controlling paper feeding operation by thefeeding mechanism 5 are incorporated. Further, a maintenance controllingcircuit 74 for controlling maintenance operation by the maintenance unit7, a scanner controlling circuit 75 for controlling scanning of arecording paper sheet by the scanner unit 8 and a communicationcontrolling circuit 76 for controlling data communication by the NFCwith the communication terminal 200 are incorporated.

In the following, communication by NFC controlled by the communicationcontrolling circuit 76, particularly reception of recording data, isdescribed. The communication controlling circuit 76 is connected to acommunication module 41 a of the antenna 41. In the ink jet printer 1,communication with the communication terminal 200 by NFC is started bythe user operating the liquid crystal display unit 37 of the operationpanel 9 to input a predetermined instruction. When a communicationstarting instruction is inputted, the communication controlling circuit76 carries out communication with the communication terminal 200. Atthis time, if the communication terminal 200 is placed into the terminalreceiving member 39 by the user and then the communication with thecommunication terminal 200 is carried out normally, then the receptionof the recording data is completed. On the other hand, even if apredetermined period of time elapses, if the communication with thecommunication terminal 200 is not carried out normally, then a messagerepresenting that communication is not carried out normally is displayedon the liquid crystal display unit 37. In this manner, recording datareceived by the antenna 41 are sent from the communication controllingcircuit 76 to the recording controlling circuit 72 similarly torecording data received from the PC 300, and the recording operation bythe printer unit 4 is controlled based on the recording data.

The ink jet printer 1 according to the present illustrative embodimentdescribed above includes a printer housing 2, a printer unit 4 disposedin the printer housing 2 for carrying out recording on a recording papersheet 100, a discharge unit 6 formed in the printer housing 2 forreceiving the recording paper sheet 100 recorded by the printer unit 4and discharged thereto, a terminal receiving member 39 provided on thedischarge unit 6 for receiving a communication terminal 200 placedtherein, and an antenna 41 for communicating with the communicationterminal 200 placed in the terminal receiving member 39 by short-rangewireless communication.

In the ink jet printer 1 according to the present illustrativeembodiment configured in such a manner as described above, the terminalreceiving member 39 in which the communication terminal 200 can bereceived is provided on the discharge unit 6 to which a recording papersheet 100 is discharged. The discharge unit 6 receives the recordingpaper sheet 100 discharged thereto and has a large opening to this side,namely, to the user side, so that the user can take out the dischargedrecording paper sheet 100 therethrough. Accordingly, it is easy for theuser to place the communication terminal 200 into such a discharge unit6 as just described. Further, since the terminal receiving member 39 isprovided on the discharge unit 6, a vacant space can be utilizedeffectively and a receiving space for the communication terminal 200 canbe assured without increasing the size of the apparatus. Further, sincethe communication terminal 200 is received in the discharge unit 6 whichhas a large opening, the communication terminal 200 can be visuallyrecognized readily by the user, and the communication terminal 200 canbe prevented from being left in the terminal receiving member 39.

Further, since the terminal receiving member 39 is provided on thedischarge tray 15 b of the discharge unit 6 on which a recording papersheet 100 recorded by the printer unit 4 is to be placed, the user canplace the communication terminal 200 readily into the terminal receivingmember 39.

Further, since the terminal receiving member 39 is a recessed portionformed on the discharge tray 15 b of the discharge unit 6 and capable ofaccommodating the communication terminal 200 therein, the communicationterminal 200 is accommodated into the recessed portion formed on thedischarge tray 15 b of the discharge unit 6. Consequently, when arecording paper sheet 100 is discharged, it is less likely to contactthe communication terminal 200.

Further, the operation panel 9 and the panel controlling board 38 forcontrolling the operation panel 9 are disposed above the discharge unit6 and the antenna 41 is disposed on the panel controlling board 38.Therefore, communication between the communication terminal 200 and theantenna 41 can be carried out reliably. Further, the panel controllingboard 38 is positioned on the reverse side of the operation panel 9.Namely, the operation panel 9 is positioned on the opposite side to thecommunication terminal 200 across the panel controlling board 38.Accordingly, wireless communication between the antenna 41 provided onthe panel controlling board 38 and the communication terminal 200 is notobstructed by the operation panel 9 which includes a large number ofconductors.

Further, since the mark 40 indicating the position of the terminalreceiving member 39 may be applied, the user can readily recognize theplace at which the communication terminal 200 is to be placed.

While the fifth illustrative embodiment of the present disclosure isdescribed above, the mode to which the present disclosure can be appliedis not limited to the illustrative embodiment described hereinabove butcan be changed suitably without departing from the subject matter of thepresent disclosure.

In particular, in a recording apparatus according to a modification, aterminal receiving member 42 is provided at a position spaced from thedischarge tray 15 b of the discharge unit 6 as shown in FIG. 14. Inparticular, referring to FIG. 14, the terminal receiving member 42 is atable provided on the discharge unit 6 and extending horizontally fromthe side wall 2 b of the printer housing 2 above the discharge tray 15 bsuch that the communication terminal 200 can be placed on the table.According to the present modification, since the terminal receivingmember 42 is provided at a position spaced from the discharge tray 15 bof the discharge unit 6, the communication terminal 200 is placed at aposition spaced from the discharge tray 15 b of the discharge unit 6.Consequently, a recording paper sheet 100 discharged along the dischargetray 15 b is less likely to contact the communication terminal 200.Further, since the distance of the communication terminal 200 to theantenna 41 provided on the panel controlling board 38 is reduced incomparison with the fifth illustrative embodiment described above,wireless communication between the antenna 41 and the communicationterminal 200 is enhanced.

In a recording apparatus according to another modification, a terminalreceiving member 43 is a groove which is formed in a region of thedischarge tray 15 b of the discharge unit 6 on the end side in thewidthwise direction of a recording paper sheet 100 perpendicular to thedischarging direction of the recording paper sheet 100 and extends inthe discharging direction of the recording paper sheet 100 as shown inFIGS. 15 and 16. In this instance, the antenna 41 is provided inparallel to the terminal receiving member 43. For example, the antenna41 can be provided in parallel to the terminal receiving member 43 on acartridge controlling board not shown, in which a cartridge controllingcircuit not shown for controlling the ink cartridges 11 is incorporated,or on a side face of the printer housing 2. According to thismodification, if the communication terminal 200 of a flattened shape isinserted into the groove formed at the end portion of the discharge unit6 in a state in which the communication terminal 200 stands uprightly,then the communication terminal 200 can be disposed along an inner sideface of the discharge unit 6. Accordingly, a discharged recording papersheet 100 is less likely to contact the communication terminal 200.

In a recording apparatus according to a further modification, an upperface of an auxiliary tray 44 serves as a terminal receiving member 45 bywhich the communication terminal 200 is received as shown in FIG. 17.The auxiliary tray 44 can move out from the discharge tray 15 b of thedischarge unit 6 to the discharging side of a recording paper sheet 100.In particular, the auxiliary tray 44 is attached to the discharge tray15 b through a pivot shaft not shown provided at a rear end portionthereof such that it is pivoted around the pivot shaft to move out tothe discharging side of a recording paper 100 from the discharge tray 15b. By this auxiliary tray 44, a recording paper sheet 100 discharged tothe discharging side is prevented from moving out from the dischargeunit 6. In this instance, the antenna 41 is provided on the auxiliarytray 44. According to the present modification, since the upper face ofthe auxiliary tray 44 is the terminal receiving member 45 by which thecommunication terminal 200 is to be received, when the communicationterminal 200 is mounted on the auxiliary tray 44 moved out from thedischarge unit 6, a recording paper sheet 100 discharged from thedischarge unit 6 is prevented with a higher degree of certainty frommoving out by the communication terminal 200. Further, since the antenna41 is provided on the auxiliary tray 44, the distance between thecommunication terminal 200 provided on the auxiliary tray 44 and theantenna 41 is very short, and consequently, wireless communicationbetween them can be carried out reliable. While the auxiliary tray 44 inthe present modification is provided for pivotal motion on the dischargetray 15 b, it may otherwise be provided for sliding movement on thedischarge tray 15 b such that it can be drawn out forwardly.

The terminal receiving member 45 may otherwise be provided on an upperface of the main tray 15 a in the inside of the paper cassette 15. Inthis instance, the antenna 41 is provided on the main tray 15 a.

Further, since the antenna 41 is connected to the communication module41 a, it can be provided on a board, in the fifth illustrativeembodiment described hereinabove, on the panel controlling board 38.Here, to provide a board for exclusive use for the antenna 41 in orderto mount the antenna 41 is not preferable because of increase of thecost, increase of the scale of the apparatus and so forth. Therefore,preferably the antenna 41 is provided on an ink cartridge board as inthe modification described hereinabove or on the control board 29. Wherethe antenna 41 is provided on the control board 29, the terminalreceiving member 45 may be provided on the discharge tray 15 b below theantenna 41.

Further, while, in the fifth illustrative embodiment describedhereinabove, NFC is applied to carry out short-range wirelesscommunication between the ink jet printer 1 and the communicationterminal 200, alternatively an RFID (Radio Frequency Identification) tagor the like may be used to carry out short-range wireless communication.Further, the communication terminal is not limited to a portabletelephone set, a smartphone or the like but may be an IC (IntegratedCircuit) card, an IC tag or the like. Further, the data communicated bythe short-range wireless communication is not limited to recording databut may be data such as log-in information to an ink jet printer.

Further, while, in the fifth illustrative embodiment describedhereinabove, the upper face of the paper cassette 15 serves as thedischarge tray 15 b, the paper cassette 15 and the discharge tray 15 bmay not be formed as a unitary member but may be provided at positionsspaced from each other while the upper face of the paper cassette 15does not serve as the discharge tray 15 b.
